The present application is entitled to priority from provisional application No. 60/499,257 filed on Aug. 29, 2003 and U.S. utility patent application publication No. 2005/0047575 published Mar. 3, 2005, U.S. utility patent application Ser. No. 10/889,410, which are incorporated by reference as if set forth in full herein.
A. Field of the Invention
The Invention is valet telephone service allowing a subscriber to place and receive telephone calls with operator assistance. Specifically, the Invention is a method and apparatus by which all calls to or by a subscriber are placed or received through a live operator using a dedicated telephone and including security features. The method and apparatus of the Invention provides convenience to the subscriber while also providing security for the subscriber's personal information.
B. Description of the Related Art
Most persons find that access to wireless or wireline communications is a necessity of daily life. A tension exists between the need for ready access to communications and the need to limit unwanted access by others. The problem is acute for those who have achieved public recognition. Such persons may enjoy little privacy due to the unwelcome attention of other persons.
Information security is, or should be, a priority for a person who has achieved public recognition. The need for information security particularly applies to telephone numbers at which the person, family members and personal contacts of the person may be reached. In the prior art, a person may employ a secretary or personal assistant to complete telephone calls and to screen incoming calls. Aside from issues of cost, a secretary or personal assistant may be of limited use in protecting the privacy of the person in situations where the person has multiple wireline and wireless telecommunication devices, including devices carried by the person. A leak of, say, the wireless telephone number of the person will allow unwelcome telephone calls that are not screened by the personal assistant, rendering the wireless telephone useless and defeating the goal of ready access to communications.
The prior art does not teach the telephone valet service method and apparatus of the Invention.
The Invention is an operator-assisted apparatus and method to handle both incoming calls and outgoing calls. A person, hereinafter a “subscriber,” subscribes to a telephone valet service offered by a service provider. In the valet telephone service of the Invention, the service provider supplies one or more dedicated wireline or dedicated wireless telephones to the subscriber as a benefit of subscription. The dedicated telephones are not general use telephones and have limited keypads and limited memories. A wireline telephone may have no keys at all and may be equipped with an automatic dialer or equivalent that automatically connects the wireline telephone to the service provider when the handset is lifted. A dedicated wireless telephone has less than a full telephone keypad and may have very few keys, such as three keys.
The dedicated wireline or wireless telephone requires few or no keys because the dedicated telephone is equipped only to place calls to or receive calls from a service provider central computer. Dedicated wireline or wireless telephone memory is programmed to store only the telephone number of the central computer and is not equipped to place a call to any other telephone number. The subscriber therefore cannot inadvertently release the telephone number of the dedicated telephone by calling a telephone that may harvest and subsequently leak the Automatic Number Identification (ANI), Electronic Serial Number (ESN), Mobile Equipment Identifier (MEID), Mobile Identification Number (MIN) or any other identifying data of the dedicated telephone that is or may be transmitted with the telephone call. In addition, loss or theft of the dedicated wireless telephone will not compromise any private information of subscriber because the dedicated wireless telephone does not and can not store any private information.
When the dedicated telephone is programmed with a telephone number by the service provider, the number is known only to the central computer of the service provider and is stored in encrypted form. The direct telephone number of the dedicated wireline or wireless telephone is not known by the subscriber, by a service provider employee or by anyone else. No one other than the central computer of the service provider may place a call to the dedicated wireline or wireless telephone. No employee of the service provider or anyone else is in a position to leak the telephone number of the dedicated wireline or wireless telephone of the subscriber. The subscriber may be assured that when the subscriber's dedicated wireline or wireless telephone rings, a human operator employed by the service provider, and no one else, will be on the other end of the telephone connection.
To provide for operator screening of all calls to the subscriber, all incoming calls to telephone numbers associated with the subscriber (referred to herein as “outside subscriber telephone numbers”) are permanently forwarded to the central computer. Examples of ‘outside subscriber telephone numbers’ include public business or home telephone numbers of subscriber. When a person calls any of the outside subscriber telephone numbers, the central computer receives the incoming call and refers the call to the human operator employed by the service provider. The operator answers and screens the incoming call in conjunction with the central computer and as directed by the subscriber and as more fully described below. If the caller is one from whom the subscriber wishes to receive calls, the operator will consult a subscriber location database comprising a ranked list of locations at which to reach subscriber. The list of locations for subscriber is ranked by time of day and day of the week. If the call survives the screening step, the operator will instruct the central computer to connect the incoming call to the subscriber at the top-ranked location for that time of day and day of the week. The central computer will consult the subscriber location database and will dial the telephone number stored in the database corresponding to the top-ranked location. The list of locations may include the dedicated wireline or wireless telephone and may include other telephones at which a subscriber may be reached.
The central computer will store an encrypted private contact database including a list of names and locations of individuals or other entities as private contacts for subscriber along with telephone numbers at which to reach the private contacts. Where a contact has more than one associated location, the locations and telephone numbers associated with the locations are ranked by time of day and day of the week. When the subscriber uses a dedicated wireline or wireless telephone to place an outgoing call, the central computer receives the outgoing call from subscriber and connects the subscriber to the human operator. The central computer receives ANI, MIN or other identifying data from the subscriber's dedicated wireline or wireless telephone and automatically identifies the subscriber. The names of the private contacts on subscriber's contact list are displayed to the operator along with the ranked locations at which to reach each private contact. Preferably the central computer retrieves the subscriber's private contact names and private contact locations and displays the contact names and locations to the operator by the time that the operator greets the subscriber. The subscriber directs the operator to connect the subscriber with a person on the subscriber's contact list. The operator selects the top-ranked location for the requested contact for the day and time of the call and completes the outgoing call to the top-ranked location for that contact.
The telephones of subscriber or of a person on the private contact list of subscriber are identified to the operator by name or location and not by telephone number. The telephone numbers for subscriber and for private contacts are never displayed to the operator and the operator never has the opportunity to view a telephone number for subscriber or for a private contact. The information security risk posed by the human operators therefore is minimized.
Security features are provided for initially entering subscriber's private contact information in a private contact database and subscriber's personal information in a subscriber location database, including locations and multiple telephone numbers at which subscriber or a private contact may be reached. When the subscriber subscribes to the service and at such other time as agreed by subscriber and service provider, a representative of the service provider travels to a location specified by the subscriber, such as the subscriber's residence or place of business. The subscriber provides to the service provider representative a list of locations and telephone numbers at which to reach subscriber ranked by day and time. The subscriber also provides to the service provider representative a list of private contacts by name, location and telephone numbers for each location for the private contacts ranked by day of the week and time of day. The subscriber representative manually enters the names, locations and telephone numbers into the memory of a laptop computer or other portable computing device supplied by the service provider. Alternatively, and for greater security, the subscriber or a personal assistant to the subscriber may enter the private contact information and subscriber information into the memory of the laptop. The laptop may be configured to download the subscriber information and private contact information by a direct connection, such as a wired connection that does not utilize a computer network, from a personal digital assistant or other computing device in which subscriber stores the information.
The service provider representative will instruct the laptop computer to encrypt the subscriber locations, telephone numbers and rankings and the private contact names, locations, telephone numbers and rankings of the subscriber database and the private contact database into an encrypted data file. The service provider representative then will connect the laptop to a wireline telephone line at the subscriber's premises. The subscriber representative will dial the central computer of the service provider directly using a modem incorporated into the laptop computer and will not use the Internet. The encrypted data file will be uploaded from the laptop to the central computer through a port. The central computer will associate the encrypted data file with the subscriber and will store the encrypted data file in encrypted form.
When the upload is complete, service provider will take any of three actions to assure the subscriber that the subscriber data is safe from theft or other information security breach. The service provider representative may give the laptop to the subscriber, thereby providing the subscriber ownership and control over the laptop and its contents. The service provider may remove the hard drive from the laptop and present the hard drive to the subscriber or destroy the hard drive. Alternatively, the service provider representative may erase the hard drive in the presence of the subscriber or the subscriber's personal representative, as by reformatting the drive. The subscriber thus can be assured that the subscriber's private information will not be released through theft or loss of the laptop, either by mistake or misadventure.
The subscriber may update securely the private contact list, the contact information for subscriber and the ranking of locations and telephone numbers at which to reach the subscriber or a contact by the means described above for initial entry of information. The subscriber also may telephone the central computer and ask the operator to be referred to an update service. The update service is an automated system administered by the central computer utilizing speech recognition to receive updated information. The central computer leads the subscriber through a series of voice-actuated menus. The central computer records the responses of the subscriber to the menus and updates the subscriber information and private contact database accordingly. The subscriber's personal information is not disclosed to a human being and the security risk of such a disclosure therefore is avoided.
All information relating to the location information and telephone numbers contained in subscriber's subscriber location database and for each listing in subscriber's private contact database is maintained in encrypted form so that the information may not be accessed if the encrypted data file is stolen or otherwise escapes from the central computer memory. The central computer is configured so that the central computer has no means to connect to the Internet. The central computer therefore is immune from Internet-based hacking attacks.
The subscriber's private contact list also may be populated using a call-trap feature. When the central computer receives an incoming telephone call, the central computer detects and extracts ANI, ESN, MEID, MIN or other data accompanying the dial string of the call, as is known in the art. The extracted data identifies the telephone number of the calling telephone. The central computer will record the extracted telephone number and refer the incoming call to the human operator. The operator verbally requests that the calling party disclose the name of the calling party and the name of the subscriber. The operator enters the name of the calling party into a computer terminal as a new contact and selects the appropriate subscriber. The central computer receives the name entered by the operator and associates the name with the telephone number extracted from the incoming call. The name and telephone number of the calling party are encrypted and added to the private contact list of the subscriber so that the subscriber may request the person by name in the future and be connected to the person by the operator.
If the name of the calling party is already in the private contact list of the subscriber but the calling telephone number is not in the database, then the calling telephone number is added at the bottom of the ranked list for the calling party.
This call-trap feature is also used to provide additional contact locations in the private contact lists of other subscribers. If the calling person attempting to reach a subscriber is listed as a private contact in the private contact lists of any of the other subscribers, then the telephone number of the calling telephone is added to the contact locations for the calling person for the private contact list of each subscriber who lists the calling person as a private contact. The call-trap feature therefore allows the private contact lists of all subscribers to be updated without active participation by any subscriber.
The ranked locations at which to reach the subscriber or a contact in the private contact database may be temporarily overridden based on calling information received by the central computer. The central computer will record the time that each call is received. For an incoming call received from a private contact to a subscriber, the service provider will record the telephone number of the telephone from which the call is received. For a predetermined period of time, for example, thirty minutes, after the central computer receives the call from the private contact to the subscriber, the central computer will override the locations at which to reach the private contact and will indicate that the location associated with the telephone number from which the call was received is the top-ranked location for that private contact. If the subscriber asks the operator to connect the subscriber to that private contact during the predetermined period of time, the operator will instruct the central computer to dial the telephone number associated with that top-ranked location.
A similar temporary override applies to the ranked list of locations and telephone numbers at which to reach the subscriber. The central computer will record the time of receipt of a call to the central computer from the subscriber along with the location from which the subscriber placed the call. If a subsequent incoming call is received for subscriber within a predetermined period of time after the call by the subscriber, the central computer will display the location from which the subscriber placed the call as the top-ranked location at which to reach the subscriber.
Other means for re-ranking the ranked lists also are disclosed.
The ranked list of locations at which to reach a subscriber may be overridden based on Global Positioning System (GPS) information received from the subscriber. The dedicated wireless telephone provided to subscriber may be equipped with a GPS receiver. The GPS receiver will determine the location of the dedicated telephone using conventional techniques of triangulation from global positioning system satellites. The dedicated telephone will periodically transmit the location information to the central computer. When an incoming call to the central computer is received for the subscriber, the location on the ranked list of locations at which to reach subscriber will be re-ranked so that the location that is closest to the most recent GPS-determined location of the dedicated wireless telephone will be displayed to the operator as the top-ranked location for subscriber.
The central computer alternatively may track the location of the subscriber using triangulation of the signal of the subscriber using cellular telephone towers, as is known in the art. The ranked list of locations at which to reach subscriber may be overridden so that the location on the ranked list in closest proximity to the dedicated wireless telephone as determined by triangulation of cellular telephone towers is displayed to the operator as the top-ranked location at which to reach subscriber.
Where the central computer tracks the location of the subscriber using GPS signals or triangulation of a cellular telephone signal, the record of the subscriber's location presents confidential information. To minimize any chance of a toss of information, the central computer erases and overwrites location information for subscriber after a predetermined period of time, for example, eight hours. The central computer therefore maintains no more than, for example, eight hours of location information for subscriber.
The Invention is valet telephone system apparatus and method allowing a subscriber to place and receive telephone calls with operator assistance. A goal of the apparatus and method of the Invention is to provide ready access by the subscriber to wireline or wireless communications while blocking unwanted access to the subscriber. A necessary corollary to blocking unwanted access is providing an appropriate level of information security to prevent release of personal information of the subscriber through either accident or misadventure.

The services provider 2 provides the subscriber with one or more dedicated telephones 10, 12, either landline or wireless, as a benefit of subscription. The dedicated telephones 10, 12 are configured to place an outgoing call only the service provider's central computer 4. The dedicated telephones 10, 12 also are configured to receive incoming calls only from the service provider's central computer 4. The central computer 4 is configured so that any call to or from the central computer 4 must be answered by human operator 18. The participation of the operator 18 therefore is necessary to place or to receive a call to or from the dedicated telephones 10, 12.
The dedicated telephones 10, 12 are not conventional general use telephones and do not have full keypads. The dedicated wire line telephone 10 may have no keys at all and may be equipped with an automatic dialer or equivalent that is activated whenever the handset is lifted. The dedicated wireless telephone 12, as shown by
The dedicated telephones 10, 12 do not store telephone numbers in memory, other than telephone numbers necessary to connect to the service provider's central computer 4. Loss or theft of a dedicated telephone 10, 12 therefore cannot jeopardize confidential information of subscriber. The telephone numbers of the dedicated wireless telephone 12 and the dedicated wireline telephone 10 are known only to the service provider's central computer 4. The central computer 4 is programmed not to disclose numbers of dedicated telephones 10, 12 to the operator 18, to the subscriber or to any other person. The telephone number of the dedicated telephone 10, 12 of subscriber therefore will not be lost, stolen or hacked. Any incoming call to subscriber using the system of the Invention must pass through the human operator 18 and be screened by the operator 18 before being connected to the subscriber.
The operator 18 may connect incoming calls to the subscriber through the dedicated telephones 10, 12. Alternatively, the operator 18 may connect incoming calls to any other telephone at which the subscriber may be reached; for example, an office telephone number. For example, the central computer 4 may advise the operator 18 to connect the incoming call to the wireline ‘office’ telephone during mornings and afternoons on weekdays, and to the dedicated wireless telephone 12 between 5:00 and 6:00 pm, during the subscriber's commute. The list of locations at which subscriber may be reached, including dedicated telephones 10, 12, are ranked by time of day and day of the week and stored as an encrypted subscriber database 30 in computer memory 32. Each location in the subscriber database 30 presented to the operator 18 has an associated telephone number. The location is displayed to the operator 18 on operator terminal 20, but the corresponding telephone number is not displayed to the operator 18 to preserve information security.
When the central computer 4 receives an incoming call to a subscriber, the central computer 4 connects the incoming call to operator 18. Operator 18 greets the caller and asks for the identity of the subscriber to whom the incoming call is directed. In response to an instruction from the operator 18, central computer 4 retrieves and decrypts the ranked list of locations at which to reach the subscriber and displays the ranked list of locations to operator 18. Consistent with the instructions of subscriber as described below, the operator 18 will select the top-ranked location at which to reach the subscriber and will instruct the central computer 4 to call the subscriber at the top-ranked location. The operator 18 then will connect the subscriber to the caller.

The laptop computer 36 stores the information in an encrypted data file readable by the central computer 4. The customer service representative uses a modem of the laptop 36 to dial the central computer 4 over a conventional wireline telephone connection. The central computer 4 receives the call at a port, associates the encrypted data file with the subscriber and stores the encrypted file as an encrypted subscriber database 30 and encrypted private contact database 34 in computer memory 32.
The subscriber may update the subscriber and private contact databases 30, 34 through another visit by a services provider representative to a location specified by subscriber, as described above relating to
To use the automated speech recognition system of
The use of the automated update system increases the security of the subscriber' information. No one has access to the numbers of the contacts in a subscriber's contact list or to the numbers of the dedicated telephones of subscriber. The subscriber can gain access to the numbers in the contact list through the service provider's administrators, but not through the operators 18. If the subscriber creates sub-accounts; for example, for family members, the subscriber does not have access to contact information associated with the sub-accounts.
The private contact database 34 also is populated by the service provider without active participation by the subscriber through use of a ‘call trap’ feature, as illustrated by
As shown by
The process of completing an outgoing call is illustrated by
The subscriber identifies a contact by name and directs the operator 18 to place a call to the contact. The operator 18 locates the name of the contact in the private contact list and instructs the central computer 4 to initiate a call to the top-ranked location for the contact. The central computer 4 wilt retrieve from the private contact database 34 the telephone number corresponding to the selected location and will decrypt and retrieved telephone number and store the decrypted telephone number in temporary memory. The central computer 4 then will dial the decrypted telephone number. If the operator 18 is not able to locate the private contact at the first location tried, the operator 18 tries the subsequent locations on the list until and operator 18 connects to the contact or the contact locations are exhausted. The operator 18 connects the subscriber to the contact after the connection to the contact is established. The central computer 4 will erase each decrypted telephone number from temporary memory after dialing the decrypted telephone number.
The receipt of an incoming call by a caller to subscriber is illustrated by
The operator 18 greets the caller and asks the name of the caller and of the subscriber. The operator 18 enters this information into the central computer. The central computer 4 identifies whether the caller is listed as an “A,” “B” or “C” contact in the subscriber's contact list, hence screening the call to subscriber. The central computer 4 will identify the classification of the caller to the operator 18. For callers on the “A” or “B” call screening lists, the central computer 4 will display to the operator 18 the contact locations for subscriber, ranked by time of day and day of the week. The operator 18 will not see the number of the subscriber, but wilt see categories, such as ‘home,’ ‘office’ or ‘cell.’ If the operator 18 answers a call to a subscriber from a caller on the subscriber's ‘A’ list, the operator 18 will instruct the central computer 4 to dial the subscriber at the top-ranked location for subscriber for that time of day and day of the week. The central computer 4 will retrieve from the subscriber database 30 the telephone number corresponding to the selected location and wilt decrypt the retrieved telephone number, store the decrypted telephone number in temporary memory, and dial the decrypted telephone number. The operator 18 then will connect the subscriber to the caller. If the operator 18 is unsuccessful at the first location called, the operator 18 will proceed along the list of locations for subscriber until the operator 18 reaches subscriber or exhausts the possible locations at which to reach subscriber. Once the connection to the subscriber is established, the operator 18 then will connect the caller to the subscriber. Depending on the preference of the subscriber, the caller on the ‘A’ list may be announced by the operator 18 or connected directly without announcement. The central computer 4 will erase each decrypted telephone number from temporary memory after dialing the decrypted telephone number.
If a caller is on the ‘B’ list, the operator 18 will call the subscriber and ask the subscriber whether the subscriber would like to speak with the caller. If so, the operator 18 will connect the caller to the subscriber. If not, the operator 18 will divert the caller to voicemail for the subscriber.
Callers on the ‘C’ list, including persons who are not otherwise categorized, are invited to leave a message on voice mail. At any time, the subscriber may direct operator 18 to move a person from one list to another and to thereby change the way incoming calls from the person are handled.
The subscriber may retrieve voice mails by calling the operator 18 and requesting voice mail. The voice mail offered by the service provider is not sequential. The voice mail is organized by caller and by time received, so that the subscriber subsequently is advised of the names and number of times each of the persons has called. The subscriber may select among the voice mails. The most recent call from a caller is presented first in the hierarchy of messages from that caller.
If subscriber location or private contact location information becomes outdated, the central computer 4 may notify the subscriber to manually update the information. The central computer 4 records the success of reaching a contacts or the subscriber and compares success in reaching the contact or the subscriber consistent with the ranked lists. If the degree of success in reaching the contact or subscriber at a particular location is less than a predetermined criterion, the service provider may notify the subscriber that the database should be updated. The updating of the database may be accomplished either through the method of a personal visit by the service provider representative or through use of the automated speech recognition system.
Alternatively, the ranked lists for subscriber locations and for private contact locations may be re-ranked permanently (or until changed by the subscriber) based on the success in placing calls to the subscriber or contact. The central computer 4 wilt record the success in reaching the subscriber and each contact at each location on the ranked list of locations at which the subscriber or the contact may be reached. The central computer 4 will move locations at which the subscriber or contact is successfully reached higher in the ranked list for the day and time of placing the call. The central computer 4 will move tower in the ranked list for the day and time those locations at which the central computer 4 has been less successful in reaching the contact or subscriber.
The central computer 4 may identify the locations from which incoming calls to the central computer 4 are made, such as incoming calls by the subscriber or by a personal contact of the subscriber. The location information appears in the dial string for the incoming call. For a call from a landline telephone, the identifying information includes the ANI. The central computer 4 can determine the geographic location of the exchange from which the call was made using the ANI. The location information for a wireless telephone will include the mobile identification number (“MIN”) and may include calling number delivery, calling name delivery, calling name and number delivery, GPS coordinates, group ANI or actual ANI. A “group ANI” is an identifier assigned to a group of cellular telephones and does not identify a particular telephone. The group ANI includes a local exchange number. The central computer 4 can determine the geographic location of the calling wireless telephone by comparing the local exchange number with a standard local exchange routing guide (‘LERG’) database.
As illustrated by
As shown by
The temporary override of the ranked list of locations applies not only to the location from which a previous call was made but also to locations in geographic proximity to the location from which the previous call was made. For example, if the contact or subscriber has multiple telephone numbers in New York, Chicago and San Francisco, a recent call from the contact or subscriber using a landline with an ANI indicating call origination in northern Illinois implies that the Chicago contact numbers are more likely to be successful than the San Francisco contact numbers. The central computer 4 will override the specified ranked location list for the contact or subscriber and place the Chicago contact numbers at or near the top of the ranked list.
The temporary override of the ranked list of locations for subscriber or a contact also applies to calls received from wireless telephones. For a contact or subscriber using a wireless telephone, the group ANI and local exchange number received from a wireless telephone for a contact or subscriber will allow the central computer 4 to determine the location of the caller. The locations for the contact or subscriber listed in the database that are in geographic proximity to the location from which the call was made therefore are likely locations at which to reach the contact. The central computer 4 will temporarily override the specified ranked location list for the contact or subscriber and place the locations in geographic proximity to the source of the previous call at or near the top of the ranked list for a predetermined period of time, for example thirty minutes, after the receipt of the first call.
As shown by
Using current technology, a dedicated wireless telephone may not be able to receive the signals of GPS satellites when the wireless telephone is inside a building. The service provider's central computer 4 will overcome this shortcoming by maintaining a record of the GPS-indicated location of the wireless telephone and inferring that the subscriber is still located at the point where the GPS information from the wireless telephone was last received. The central computer 4 automatically will override the subscriber-specified locations at which to reach subscriber to indicate as the top-ranked location the location on the ranked list that is closest to the last known position of the GPS-equipped wireless telephone.
Recording the subscriber's location using a GPS-equipped wireless telephone introduces its own security concerns. A subscriber may be reluctant to allow a service provider to use the GPS-equipped wireless telephones to track the movement of the subscriber. To overcome this reluctance, the central computer 4 may be programmed to continuously overwrite the GPS location information so that, for example, a rolling eight hours of GPS location information is stored in computer memory. At the end of eight hours, GPS location information is erased and the memory is overwritten. The service provider will have no more than eight hours of GPS information relating to the subscriber.
The central computer 4 alternatively may track the location of the subscriber using triangulation among wireless telephone towers, as is known in the art, and may use the resulting subscriber location information as described above for GPS tracking information. If the service provider collects location information of the subscriber using wireless telephone tower triangulation, the central computer 4 will be programmed to provide similar information security, as by periodically erasing and overwriting the location information in computer memory.
In describing the above embodiments of the invention, specific terminology was selected for the sake of clarity. However, the invention is not intended to be limited to the specific terms so selected, and it is to be understood that each specific term includes all technical equivalents that operate in a similar manner to accomplish a similar purpose.
